Be it known thatI, TALBERT R. MIcnEALs,

.a citizen of the United States of America, re-

siding at )[onongahela City, in the countyA of Washington and State of Pennsylvania, have invented certain new and usefiil Improvements in Glass-XVorking Machinery, of which the following is a specification, reference being had therein to the accompanying drawings. Y y

This invention relates to certain new and useful improvements in glass-machines; and it has for its object to provide a machine for forming sheet or plate glass by pressing the same instead of performing the work -in the manner which is no'w done.

The 'invention aims to provide such a machine in which the plate-glass when removed from the table is annealed in a special manner and the grinding which is usually done on glass of this character dispensed with.

To this end the invention consists, essentially, in a tension-table, above which is arranged the plunger which carries the molding-slab, and in the novel form of construc- -tion` whereby this plunger is operated, to-

gether with the means for removing the glass plate from the table, where it may be engaged bythe snaps by which the plate is handled while annealing.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification,and wherein like figures ofreference indicate similar parts throughout the several-v iews,in which- Figure 1 is a 'perspective View of my im- I proved glasspress, partially broken away.`

Fig. 2 is a longitudinal sectional `view. Fig. 3 is a transverse vertical sectional view taken through the plunger and table. Fig. 4:. is a like view taken through the table on a line in front of the plunger. Fig. 5 is a sectional view of the bracket through which the plunger-rod operates and showing a detail view of the -carn -wheel for operating the plunger. Figs. 6, 7, and 8 are detail perspective views of the snap and stand employed for annealing the glass. To put my invention into practice, I provide a suitable box or casing 1, upon which is supported and has secured thereto the frame 2. Arranged in the top of thecasing 1, near its forward end, isa depressible table 3, which is normally `iush with the top of the said casing and is supported by vertical rods orstandards 4, having coil-springs 5, arranged thereonwithin the casing, which serve to` return the depressible table to its normal position after the weight of the plunger has been relieved from the'same; Arranged centrally o f the table `3 is 'the receiving-slab 6, which is composed of highly-polished stone, steel, or other suitablefmaterial.l The molten glass from placed upon this slab 6 and is flattened into form by means of the forming-slab 7, which 'which the sheet orplate is to be formed is to this quadrangular frame, so that no impediment will be offered to the close engagement of the two slabs, and this may be accomplished by forming the two lugs 11 on the slab 7 and forming the quadrangular frame 10 with lugs 12, having bolts 14 rigidly secured therein and operatingin the lugs 11. In order to guide the forming-slab 7, I also provide the same with lugs 15, which engage in the grooved standards 16, supported by the table 3 and acting as guides for the saidl forming-slab.' The forming-slab and plunger are operated by means of the longitudinally-extending shaft 17, journaled in the -framework and having a four-armed wheel 18 nounted upon its forward end. To one of these arms is pivotally connected 'the one end of the lever 19, the other end of which is piv otally connected to the inner face of the plunger-rod 8. This shaft may be provided on its rear end with a' counterbalancef'wheel 20. This shaft 17 has rigidly mounted thereon a sprocket-wheel 2l to receive the sprocket chain 22, engaging the same 'and engaging the sprocket-wheel 23, which is rigidly mounted upon a longitudinally-extending shaft24, also mounted in the frame 2 and directly un- ICO the cross-head Ell after passing't'hrough the cross-.piece 82 of the frame. To this crosshead l is connected the one end of the cord o1' chain 53,the otherend of which is attached to a spool Si, rigidly mounted upon a transverselyextending shaft 35, which is ljournaled in the framework and 4is provided on iis one end with an operating-wheel 3C, havingalockinglever 37, which engages against the stop or traine 2. The clutch is held no'mualtyinengagement by means of coil-springs 39, arranged upon the rods 8O between the crossv piece 32 and the cross-head 29. Arranged upon the top of the box or casing 1, directly in line with the slab 6 and at the rear thereof, is a carrier and de'liverer 4:0, provided with a forked or bifurcated forward end 41, forming the springs which are adapted to engage underneath the sheet or plate of glass and upon which the same rests while it is being carried forward to the snap. This carrier and deliverer is provided on its upper" face with ribs 42, which serve the same purpose as cogs and are adapted to be eng-aged by the ribbed or cogged wheel 43, mounted upon a transversely-extending shaft dtv-1, journaled in suitable bearings 45, provided therefor on the frame 42, and which is provided on its one end with an operatingehand le i6. Thus the carrier and deliverer is moved forward or backward, according to the direction in wh ich the shaft i is rotated. For the purpose of elevating the sheetor plate of glass' after thesame has been formed upon the slabil provide thisslab at `eachof its corners with 'cut-away pol'- -tions, in which are locatedthe ,verticallymoving elevatingpins 47, which conform to the shape of the cui .iway portions and eemplete a perfect square or other shapeof slab which may be used. y These elevating-pins t7 are connected to a plate itl, arranged underneath the depressible table 3, and carries a bearing 4:9, in which is -journaled a cog or 'spur gear 50, adapted to be engaged by' the spur-gear 5l, which is eccentrically mounted upon the transversoly-extendingshaft 5:?, the latter heilig journaled in the box or casing l and provided on its one end with the operating-wheel 53 and with the locking-lever 54:, which engages against the stop or lug 55, provided therefor on the side of the saidbox or casing. .1

After the plate or sheet offfglass has been formed upon the slab 6 and the formingslab vto its former position, andasui'licient quan- A(i, 7, and S of the drawings, comprising a suitable base 55, to which are secured the stand- 8o ards 56, inthe upper end of which is journa'led a shaft 57, carrying on its one end a harp or fork 58 and on its other end provided with an operating-crank 59. Swiveled near the opposite end of the base 55 is a standard S5 GO, provided in its upper end with a grooye to receive the shaft Gl,which carries the'snapf y U2. This snap G2 may be provided wijthvoue "j,

.closed and one open face and is used to 1ref `9o ceivet-he plate or sheet of glass from the carrier and deliverer.\. Afterit has received Athe` plate the shaft is turned soast'o' briiig the snap in aliuement with; theharp 5S and permit the harpto enter thelsaid snap. The two will theurevolve'iu unison during-the annealing of the glass, and -wheu the aunealing has beeniinished 'the snap will be turned so as to deposit the plateor sheet ou the harp or fork 5S, and the snap is then withdrawn, the said sheet or plate being removed from the harp orfoik in any desired manner. By such a machine a perfect sheet or plate of glass may be formed at each stroke of the plunger-rod, which brings the forminglslab 7 into engagement with the molten glass pre! viously placed upon the receiving-slab G, and as the eccentric connection of the plungerrod with the lever 1) and wheel 1S causes the forming-slab to be elevated the sheet or plate of glass just formed is elevated from' the slab 6 in the manner heretofore described, the carrier and deli-verer is run forward, so that the plate or sheetl'lmay be engaged by the snap, the carrier air( -d'elivercr returned ICO IIO

tity of molten glass again placed upon the receiving-slab G to be in position for the forming-slab 7 upon its succeeding` downward stroke. The complete revolution ofthe wheel 1S is permitted byreasou ot' the table 3 being Vdepressible, and when the center of the revelution has been passcd`the springs 5 will immediately return the tablel vto its normal position.

In case it is desired tosuspend the move-v ment of the forming-slab? the shaft is rotated so as to wind thcchain upon its spool 3l, and consequently causes the crosshead 29 to withdraw the -cluch from its en gagement, so that the pulley 25 will revolve freely upon the shaft without rotating the sprocket 2i therewith. The shaft is locked in its position by means of the lever 37, and whenithe latter is disengaged from its stop 3S ISO the springs 39 will return the clutch into e1= gagement and again start the operation of the forming-slab.
